January 1, 2015: Updated CSS to use CSS3 for lists of sessions and categories on the home, sessions, and categories pages.

July 6, 2014:

Modified print style sheet to hide elements other than the title, text, and copyright.

Added the ability to view multiple sessions at once. Use e.g. 5-9 or e.g. 21,34,67.

Combining the two changes above, it’s now possible to create your own PDFs of any or all sessions, customized as you wish (i.e., showing [or not] question numbers, categories, etc.). Windows users, see here if you need help creating PDFs. Mac and Linux users can print to PDF.

Added links (shown with “↥”) on category and multi-session pages for putting the current question/answer at the top of the page so that it’s possible to link to a specific Q/A within a category (e.g. Cosmology 13.5) or on a page showing multiple sessions (e.g. 21, 34, 67#21.24).
